Change the Boot Mode

This section describes the available boot modes available and contains instructions

for changing the boot mode from the craft port using a diagnostic PC.

Boot Modes

Three boot modes (0 through 2) exist and are described in the following list:

0 - Skip BootP (Standalone mode) – This mode bypasses the boot mode when



you power on the GoQAM. Use the Skip BootP mode when operating in

Standalone mode, when provisioning and monitoring the GoQAM from the

front panel or the craft port, or when operating without the control of the DNCS.

This mode skips the BOOTP and TFTP processes and jumps directly to the

application code.

1 - Attempt BootP One Time (Attempt Bootp Once mode) – This mode is not



normally used in network operation. If used when the GoQAM is connected to

the network and the network connection is lost or reset, the GoQAM must be

rebooted. This mode attempts each BOOTP and TFTP step only once. If a failure

occurs during any step, the step is skipped; the GoQAM attempts the remaining

steps and eventually attempts to start the application. If the BOOTP and/or

configuration file TFTP steps are aborted due to errors, the GoQAM may not

communicate with the DNCS.

2 - Bootp Until Successful (Boot Until Successful mode) – This is the default



mode. This mode continues to boot until the GoQAM receives an IP address and

all download images. This setting is useful when upgrading the software.

Booting until successful ensures that the GoQAM completes all startup

procedures successfully. Use the standard mode (boot forever until successful)

when a network controller such as the DNCS monitors and provisions the

GoQAM through the Ethernet port. This mode attempts to boot and to TFTP the

configuration file and any requested boot and/or application code files until the

entire process is successful. If an error occurs at any step, the GoQAM restarts

until a successful boot occurs.

Important! Do not select this setting when operating the GoQAM outside a

DNCS environment.
